Ouestion, I am having muscle twitching upper and lower body. Arm tremors, lack of energy and I feel like I'm shaking inside. I have a appoiment this Monday with neurologist. I seen my PCP he said except for the twitching my pyscial examine was normal. He drew routine blod it was all normal. Anyone have any thoughts? At this point no breathing or swallowing problems but I am to nervous to eat or sleep, thanks, Mike.
